解析:动词变现在分词可有如下口诀:一添一去y不变. 一添指双写规则;一去指去掉不发音字母e规则;y不变指要与名词变复数区分开。
二、丢掉be动词或忘记把动词变成现在分词
例:1、 Look,two children flying.(fly) a kite in the park.
2 、Li Mingisnt read ( not read) a book in bed now.
答案:1 are flying 2 isnt reading
解析:现在进行时肯定句的结构规律为: be+现在分词,缺一不可。这一点必须牢记。
三、对动词或动词词组提问时丢掉doing
例:1 、The students are singing in the room.(对划线部分提问)
What are the students in the room?
答案:What are the students doing in the room?
解析:现在进行时态中对动作提问可记住此句式What +be +主语+doing+其它?
或简写为What......doing......?句式。
四、现在进行时态的选择疑问句中易忽视or后用现在分词形式
例:孩子们在跑还是在跳?
Are the children running or jump?
答案:Are the children running or jumping?
解析: or连接的是两个并列成分,动词形式须一致。
